So, what exactly is this Routing concept, and how does it function?
Examine Figure 1-1l shown below and answer the following questions: East Office (Bulding B) network address 192 168.1.0 West Office (Bulding A) network address 192.168 20 Distance B Between Routerd and Switcho is 3 meters PCO with low data transmission Switcho Routero PC1 2950 model Routert Distance A Between Router1 and Routero is 300 meters. PC2 Figure 1-1: Local Area Network Topology 6) Propose the appropriate cable that should be used to connect the Distance A and Distance В. (ii) Discuss TWO (2) differences between the cables that you have proposed in Question 1 c) (i) above.
59. Consider the network in Figure 3.56, using link-state routing. Suppose the B-F link fails, and the following then occur in sequence: (a) Node H is added to the right side with a connection to G. (b) Node D is added to the left side with a connection to C. (c) A new link D-A is added. The failed B-F link is now restored. Describe what link-state packets will flood back and forth. Assume that the initial sequence number at all nodes is 1, that no packets time out, and that both ends of a link use the same sequence number in their LSP for that link, greater than any sequence number either used before.

Consider the throughput example presented in the figure below. Now suppose that there are 4 client-server pairs. Denote Rs1, Rs2, Rs3,Rs4 ,Rc1 ,Rc2 ,Rc3, Rc4 and R for the rates of the server links, client links, and network link. Assume all other links have abundant capacity and that there is no other traffic in the network besides the traffic generated by the 4 client-server pairs. Question:derive a general expression for throughput for the Client Server pair 1, in terms of Rsi, ,Rciand R.
P16. Consider the following network. ISP B provides national backbone service to regional ISP A. ISP C provides national backbone service to regional ISP D. Each ISP consists of one AS. B and C peer with each other in two places using BGP. Consider traffic going from A to D. B would prefer to hand that traffic over to C on the West Coast (so that C would have to absorb the cost of carrying the traffic cross-country), while C would prefer to get the traffic via its East Coast peering point with B (so that B would have carried the traffic across the country). What BGP mechanism might C use, so that B would hand over A-to-D traffic at its East Coast peering point? To answer this question, you will need to dig into the BGP specification. ISP A ISP B ISP C XISP D
Consider the throughput example presented in the figure below. Now suppose that there are 4 client-server pairs. Denote RS1, RS2, RS3, RS4, RC1, RC2, RC3, RC4 and R for the rates of the server links, client links, and network link. Assume all other links have abundant capacity and that there is no other traffic in the network besides the traffic generated by the 4 client-server pairs. Question:Assume that for i = {1,2,3,4}, RSi = RCi = R. Furthermore, assume that all routers have infinite buffer capacity, meaning that packets are never dropped and are eventually forwarded by a router. What is the throughput for the Client Server pair 1? What is the throughput for Client Server pair 3?
Explain the pros and cons of using traffic engineering as a possible answer to the problem of network links getting backed up.
